Stubby is right...gotta stay on them if you want to consistently catch...you can catch 40 blues one morning and go to the same spot/same conditions the next day and catch 4...nothing beats time on the water...eventually you will learn where they go,when and why...make some fishing contacts on your lake and start sharing info. Rayburn has some good humps and points...go to where the sandbass and hybrids are biting and fish under and around them. this time of year they are easy to find...spring time blues a lot harder.
There is a fine line between fishing and floating around like an idiot!!
